Appuea'ci' nmeatrune 23, 1924 Serial no. 721,640.

T 0 all whom ifmayzconcem Beit known that I; HARRY V .-I{NOXVL TON, a citizen, of the United States of America; and a'res-identot-Lowell, in tlie county of Middlesex and- State of 'Massachusetts, have invented certain new-and useful Improvements in Picker Air-Intakes; of which the following is" a'specifioation- This invention relates to air intahes'for i0 ickers; theobj'eet-of the invention. being the provision of means whereby all the air delivered to the picker machinery will be drawn; from the 1 outside of? the building thereby leaving unchanged the atmospheric conditionswithin the pick-er room. 7

The inventionconsists of certain novel features of construction and arrangement of parts wl'iieh-wil l 'be understood readily by reierenceto the description ofthedra'w-ings and to the claimstobe' hereinafter given.

1 For the purpose of il hts'tratingtthe' invention-, one preferred-form thereot' is illustrated in the drawings, this. form having been found to give satisfactory and reliable resultsalt-hough it is to be understood that the various instrumentalities: of which the invention consists can; be varlo'us'ly arranged" and} organized and the invention. is not liinitedto the-precise arrangement'and organization of these instriunen-talities asherein shown and described except 5 as required by thescope of the" appendediclaims.

Of the drawings: Figure 1 represents a diagram in: plan of a a pickerroom with: the machines-therein installed provided with: a system for. providing air therefor" embodying the principles of the presen't 'inventione Figure 2 repre ents a d-iagran'i cathesame" in elev'ation Figure S represLents avertfical section of the mouth piece "through which air is carried to 'thezpijckerfi Figur'e t represents aztransverse'section of 4 same on line 4; 4 on Fi s;

Figure 5 represents an' elevation of the mouth piece through which airis carried to another. portion o'f'the' picker machinery.

Figure ,6 represents an en'd'elevation' of the same.

Figure 7 represents an elevation of' thej mouth piece. thronghrwhich. airis carried to thebreaker 9i tiller-pickermachinery,

Figure 8 represents a transversesection of the same on line 8; 8 on Fig.7, and

Figure 9 representsa vertical section of "thro-uglrout the several figures o't the dr'aw- In the drawings 1O, 1 0 are the side walls of a picker room and 11 the floor thereof.

Below the floor 11 are a'pjlurality of pipes 12 all connected at one end to a main air supply pipe '13 one'end of'which extends through a side walllO and is bent downwardly as at ldto shed'water.

Near the open outer end ot'the main pipe 13- is a damper 15" which maybe closed. when the picker machinery is not in use.

hen the picker machinery is in operation the damper 15 is opened, thereby permitting' all fl011'1 theoutside of the building to be drawn through the pipe 13 and branch pipes 12 to the various parts of the picker machinery, such as the'breake'r" 16, the first picker-17, and the finishingpicker 18.

Each finishing picker 18 has a. mouth piece 19 installed therein of the construction shown in Figures 3 and 4, the lower end 20' of'which communicates through the floor 11 with a lateral extension 12 from one o'tthe branch pipes 12;

V This mouth piece has a discharge opening'21 near the'top thereof which extends the entire widthot the picker and beneath this opening 21 said mouth piece has two hollow triangular arms22whi'ch are adapted to deliver air to both sides'oi the picker, thus dispensing with the grid doors, usually usedfor this purp"o'se I i Above the. opening 21 andexten'ding from the top of-the mouth-piece 19'is a plate 2-3 having at its'outer end a vertical flan ea, said plate and flange forming 'a shield! to prevent air entering the picker through'the' apron '25.

The beater 26 of each picker is provided with a: shield 27 surrounding the opposite ends of its" shaft 28", thereby preventing picker around: said shaft.

These shields 27536 may-tee of any-Sim? ple construction and it is believed therefore that detailed illustration thereof is unnecessary.

If more than one picker 18 is used in the system, another month piece 19 is provided for each picker.

As the first picker 17 has no apron 25 a mouth piece 31 is provided therefor similar to that shown in Figs. 5 and 6.

The lower end 32 communicates through the floor 11 with a lateral extension 32* from one of the branch pipes 12 and its upper end is closed except at the sides thereof, said sides having the oppositely disposed discharge openings 33 which deliver air to both sides of said picker 17.

Each branch pipe 12 is also provided with a lateral extension 341 which extends through the floor 11 and communicates with the lower endof the mouth piece 35 and has a side discharge openings 37 at opposite ends thereof.

These discharge openings 36, 37 are adapted to deliver air to the breaker 16 both at the top and at both sides thereof.

The mouth piece 35 may be formed in one unit as shown in Figs. 7 and 8, or the vertical wall 38 may be omitted, one of the imperforate walls of the machine being substituted therefor.

In the latter case the inclined wall 39 would be in a separate piece and secured to the machine thereby completing the dis charge passage.

Heretofore the air passing through the picker machines has been taken from the picker room but this is very objectionable as this air is replaced by air from other rooms where it has been heated and humidified.

The cost of fuel to heat this air is considerable and this expense is saved where the air for the pickers is drawn from the outside ofthe building.

By using this system not only is there a great economy in fuel but much better results are obtained as the quality of the work delivered from the pickers is greatly improved in view of the fact that it is possible to maintain a more even humidity in the picker room.

Better laps are obtained which are more even in weight, this being due to the fact that the picker has delivered to it all the air'that it requires and the supply is constant.

There is no necessity of heating the air delivered from this system no matter what the temperature of the outside atmosphere may be.

It has been found that the improved quality of the laps is felt throughout the mill and very superior'yarn is finally produced.

It is believed that the operation and many advantages of the invention will be appar ing with the inner end of said pipe and through which said air is adapted to be discharged into said picker; and means for closingsaid pipe when the picker is not operatin 3.
